Embodiment Construction
[0044] The construction method of the underground diaphragm wall in the tunnel includes the following steps.
[0045] Step 1: Construction of the guide wall; the construction process of the guide wall in the tunnel is: installation of the upper support of the tunnel → measuring and setting out → breaking the initial support structure at the bottom of the tunnel → digging trenches → binding the steel bars of the guide wall → setting up the formwork → pouring the concrete of the guide wall →Remove the formwork and install cross braces; during the construction of the guide wall in the tunnel, manual excavation is used to construct the guide wall due to the limited underground working space. The stability will be affected to a certain extent. I22a I-beam or Φ36 lead screw is used to support the upper part of the tunnel.
[0046] Step 2: Grooving: A small hydraulic grooving machine is used for grooving. A drill bit is installed in the center of the mechanical grab to increase the d...
